15W40 engine oil sachet: the mixed-fleet grade in a glovebox pouch
This 15W40 engine oil sachet carries 500ml of Greyhound G-Power 15W40 CI4, the most widely specified grade on South African roads, in a sealed foil pouch. Hilux, Ranger, Isuzu KB and D-Max, Quantum, NP200, Sprinter and most trucks built before the low-SAPS era all call for a 15W-40 diesel oil, and the same oil is approved for petrol engines, which is why fleets standardise on it.
Who buys the sachet
- Bakkie and minibus taxi owners topping up between services on long routes.
- Fleet controllers who issue one sachet per vehicle rather than leaving open containers in the yard.
- Filling stations, spaza shops and hardware counters selling single top-ups.
- Construction and farm sites with mixed diesel plant that shares one grade.
What CI-4 means for you
API CI-4 is the heavy-duty diesel category written for EGR engines and high soot loads. It keeps soot in suspension, protects against bore polish and holds TBN for long drains in poor fuel areas. Paired with the SL petrol rating, one sachet covers both the diesel bakkie and the petrol runabout in the same household.

How to use it
Engine off, level ground, check the dipstick. Tear the notch and pour through the filler. Wait a minute and check again; most bakkie sumps move from the low mark to the middle with one sachet. Do not top up a low-SAPS engine (DPF fitted) with CI-4; those need our low-ash range.
